SIM300CZ

红外遥控解码，基于51单片机的例程，简单实用，我在学习单片机的时候用到的(Infrared remote control decoding, based on 51 MCU routine, simple and practical, I used the time to learn microcontroller)

简单的继电保护控制源代码，变压器及线路保护类(Simple relay control source code)

大家好，这是关于密码锁的电路图，需要的话可以参考下( 允许输入拉丁字符的拼音 英语 中文(简体) 日语 Hello, everybody, this is a circuit diagram of the combination lock, if necessary, can refer to the following 允许输入拉丁字符的拼音 英语 中文(简体) 日语 Hello, everybody, this is a circuit diagram of the combination lock, if necessary, can refer to the following)

振幅调制,角度调制，频率调制等几个源程序，模拟通信系统(Amplitude modulation, angle modulation, frequency modulation, such as source code, analog communication systems)

本程序主要是对小车进行左转控制，有三种方法左轮抱死，右轮抱死，或者左轮后退右轮前进，三种方式进行左转(This procedure is mainly to control the car on the left, there are three ways, revolver, holding in death of the wheel lock, right or left back right wheel to go forward, three ways to turn left)

C8051f340 8位pwm波形输出 占空比可调节(C8051f340 8bit output )

液晶240*128驱动 用的是PIC单片机 但是可以改 51单片机 里面驱动都一样 就是 拿过来就可以用 (LCD 240* 128 drive using a PIC microcontroller, but can be changed inside the microcomputer 51 is to take over the same driver can be used)

可以产生幅度、频率可调的方波，频率50hz到1M(Can produce the amplitude, frequency adjustable Fang Bo, frequency of 50Hz to 1M)

SD卡2.0协议的详细资料，可用与SPI使用(The details of the SD card 2.0 protocol can be used with SPI)

智能车驱动程序，利用ULN2003A作为隔离，控制BTS7960驱动芯片，实现驱动，程序有限幅，反向等。(Smart car drivers, use ULN2003A as isolation, control BTS7960 driver chip, drivers, programs limiter, reverse and so on.)
